For silvers, Our Beloved Masters changed the EC/C+ rules so that *all* EC/C+ are free at T-24, including international. The tradeoff is that the meager discounts we got when we had to pay for EC/C+ seats at T-24.00000001 (50% domestic and 25% intl, IIRC) is now 0%. This change was unrolled as part of the announcement of C+ a few months ago.
